Answer 1

Even Integers:

1) Integers are the subset of the real number which can be represented by {0, ±1, ±2, ±3,.............±∞}

2) Even integers are the number which is divisible by 2 or whose one of the factors is 2.

3) So every even number is represented as 2q where q can be any integer.

Every even integer is of the form ​2q.
